Shin-Etsu KE-1830 Heat-Cure Silicone Adhesive, 20 Kg

Description

KE-1830 adhesive is a one-part Shin-Etsu silicone adhesive and sealant supplied in a 20 Kg pail for production teams that need heat-cured bonding, sealing, potting, or form-in-place gasketing. The material cures to a tough elastomer and is built for applications where unprimed adhesion to metals, plastics, glass, and ceramics is valuable.

KE-1830 adhesive For Electronics Sealing

Shin-Etsu lists KE-1830 as a high-viscosity, one-component addition-cure adhesive and sealant with a working time of 90 days at room temperature. That long room-temperature working window helps purchasing and production teams manage staged assembly while still using a heat-cure silicone system. Typical applications include form-in-place gasketing and sealing electronics, especially where a flexible cured rubber is preferred over a rigid encapsulant.

KE-1830 adhesive Cure And Property Profile

Published data reports a cure condition of 1 hour at 120 C, Shore A hardness of 40, tensile strength of 4.30 MPa, and usable temperature range of -40 C to +180 C. These values are reference properties rather than final design approval, so each assembly should be tested under its own materials, surface preparation, bond line, and cure schedule. The off-white color and high viscosity make the product suitable for controlled placement in electronic sealing and gasketing work.

Production Use Notes

Use KE-1830 where a one-part format reduces metering complexity and the assembly can be exposed to the required heat cure. Keep the pail closed when not in use, follow cold-storage guidance when required, and avoid changing cure time or temperature without testing the final bond and seal performance. The long pot life does not remove the need for clean surfaces and repeatable dispensing.

Manufacturer And Ordering Context

Shin-Etsu product information is available through Shin-Etsu Silicone. Choose this 20 Kg package for higher-volume sealing, gasketing, and electronics production where a heat-cure silicone adhesive has already been specified or approved by engineering.
